Using smaller volumes of contrast media (CM) in CT angiography (CTA) is desirable in terms of cost reduction and prevention of contrast-induced nephropathy (CIN). The purpose was to evaluate the feasibility of low CM volume in CTA of the aorta. 77 patients referred for CTA of the aorta ...

Contrast-medium protocol optimizations were built on the foundational belief in a triad of relevant variables categorized by the early researchers: namely patient-related factors, CT-scan-related factors, and contrast-medium-injection-related factors. In this review, evidence is provided that a fourth ...
(TD) between bolus-tracking and the acquisition of the first volume scan, which is less than 2 s for most scanners17. Hence, in order to acquire V1 close to the baseline enhancement of the pulmonary artery, bolus tracking was done in the right ventricle (RV) instead of the pulmonary ...
We found that outpatients undergoing abdominal CT scan preferred water only as oral contrast above the positive oral contrast. This does not influence image quality. One observer experienced slightly less confidence in the evaluation of the GI tract, peritoneum, retroperitoneum and lymph nodes; this ...

"We believe that on the bases of indication, for evaluation of vascular structures, a scout can provide scan length, and a test-bolus, scan duration, automatic selection of tube current and potential will have more influence on an individual amount of iodine contrast volume and concentration to...

Relative microvascular blood volume (MBV) is determined as the mean signal intensity in decibels after subtraction of the signal intensity before the contrast injection (Mulder et al., 2008; Tobin et al., 2010). After stimulation (e.g., glucose load), the magnitude of the CR is derived fro...
